Another example of how this could be applicable pertains to chondrule formation. Chondrules are molten grains found in meteorites, whose formation requires rapid heating to \(\sim \) 2000 K [1]}. While there is no consensus on this topic, it has been proposed that their creation takes place in magnetic current sheets in protoplanetary disks, which may reach temperatures \(>1500\)  K [2]}, [3]}. Those high temperatures would trigger the thermal ionization of K and Na, leading to a sharp decrease in resistivities. Subsequently, the downward gradient in resistivities may create an instability that would allow the magnetic field to pile up in the current sheet [4]}. That phenomenon may be the origin of thunderclaps and extremely localized heating of the grains and gas [5]}, which are necessary conditions for chrondrule formation. However, readers should refer to [6]}, who argue that insufficient alkali metals would evaporate from grains to allow for this instability to act.
